LOS ANGELES - A series of small earthquakes centered in the lightly populated desert rattled parts of Southern California on Monday, the U.S. Geological Survey reported.

The seven quakes, including one measuring a magnitude of 4.7, were centered about 12 miles southeast of Anza, in Riverside County, and 23 miles south of Palm Springs, but were felt over a wide area of Southern California. They were felt in Sequoia National Park, about 250 miles away, the Los Angeles Times reported.

The quakes were deep - about seven to eight miles - and occurred within 20 minutes of each other about 10 a.m. PT. There were no reports of injury or damage.

In Los Angeles, one quake produced a rolling motion.

In the USA TODAY bureau, on the ninth floor of an office building just north of Los Angeles International Airport, the quake caused window blinds to jangle. The rolling motion lasted about 10 seconds, inducing a momentary seasick feeling in some workers.

The U-T San Diego newspaper quotes Jim Eskidge, a resident of Fletcher Hills in the eastern part of San Diego County, as saying "the ground shook pretty good, and the windows shook good."

The USGS initially registered the first quake as 5.2 magnitude before revising it downward. The smallest of the quakes measured 2.5 magnitude.
